I've been searching for tankbags, rear cases, etc that can carry my pup along with me. So far I've only come up with the Bagster Friendy but I can't seem to find anyone in the US who sells them. I've been considering finding an old rear hardcase luggage and modifying it to fit a pooch, but does anyone have any other options? My dog is only about 11-15lbs wet, pretty tiny and likes to go in cars. I know I'd have to wean her onto the bike but any thoughts would be appreciated, thanks!
